Abstract:
Objective:To evaluate the associations between CYP24A1 genetic polymorphisms and related risks on breast cancer among postmenopausal women.Methods:We carried out a population-based case-control study to include 1 134 postmenopausal women (589 cases and 545 controls) from Wuxi, Jiangsu province and to explore the association between CYP24A1 polymorphisms and related risks on breast cancer. Seven CYP24A1 variants (rs2209314, rs2585428, rs2762941, rs3787555, rs4909959, rs912505 and rs927650) were genotyped by Sequenom MassARRAY platform. Logistic regression method was used to estimate the CYP24A1 genetic variants and susceptibility of breast cancer. Loci-loci interactions were evaluated by a generalized multifactor dimensionality reduction (GMDR) method.Results:Result showed that rs2209314, rs2585428, rs2762941, rs3787555, rs4909959, rs912505 and rs927650 of CYP24A1 were not associated with breast cancer under the codominant, dominant, recessive or additive models. Among the population with <80 cm waist circumstance, rs2585428 was associated with the reduced risks on breast cancer ( OR=0.64, 95 %CI: 0.42-0.96). Similar negative association was observed for rs3787555 ( OR=0.58, 95 %CI: 0.38-0.87). The genotypes of rs2585428, rs3787555 and rs4909959 showed significant interactions with waist circumstance on the risk of breast cancer. Also, rs2209314, rs3787555 and rs912505 in CYP24A1 could alter the risk of breast cancer by way of loci-loci interaction. Conclusion:CYP24A1 variants rs2585428 and rs3787555 were associated with risks of susceptibility on breast cancer, among postmenopausal women.
